The friction clutch includes a first clutching surface and a second clutching surface configured to be pressed against each other. Friction between the surfaces needs to be overcome for one surface to rotate relative to the other. The first clutching surface is configured to be axially and rotationally fixed relative to the steering shaft. The second clutching surface is configured to allow relative rotational movement between such surface and the steering shaft. When unlocked the second clutching surface rotates with the first clutching surface and steering shaft due to friction. When locked, the rotational position of the second clutching surface is fixed so as not to rotate with the first clutching surface and steering shaft. The friction must be overcome for the steering shaft to rotate. The friction can be overcome by application of sufficient external torque at the steering wheel. A controller controls locking and unlocking.
